In the title compound, C22H18O3, an intra­molecular O—H⋯O hydrogen bond stabilizes the mol­ecular structure, forming an S(6) ring motif. The central benzene ring forms a dihedral angle of 64.74 (5)° with the phenyl ring and a dihedral angle of 5.58 (5)° with the terminal benzene ring. In the crystal, mol­ecules are linked into columns along the a axis via inter­molecular C—H⋯O hydrogen bonds. C—H⋯π inter­actions involving the centroid of the hy­droxy-substituted benzene ring further stabilize the crystal structure.
